Association study of comprehensive geriatric assessment and the mortality rate of elder inpatients with decompensated chronic heart failure

Abstract

Objective To assess the relationship between the comprehensive geriatric assessment (CGA) score and the mortality rate of elder inpatients with decompensated chronic heart failure (CHF). Methods One hundred and thirty-four elder inpatients who were more than 75 years and diagnosed with decompensated CHF in Department of Geriatrics from July 2013 to July 2015 were included and assessed by CGA. Logistic regression analysis was used to evaluate the effects of CGA scores on the mortality rate of elderly inpatients with decompensated CHF. Results Significant differences between death patients and survival patients were found in age, serum lipid, atrial flutter/atrial fibrillation, mean blood pressure and cardiac function classification (P<0.05). In the CGA scoring system, significant differences between death patients and survival patients were found in health assessment, ability of daily life and mental state (P<0.05). The significant difference of the CGA scores between death patients and survival patients appeared in the score constitution(P<0.001). In Logistic regression analysis, age, lipid level, cardiac function classification, CGA score were screened as the risk factors of the death in the decompensated CHF inpatients, which together influenced the prognosis of inpatients, so the value of P(bilateral)<0.05. Conclusions In the study of elder inpatients with decompensated CHF, age, serum lipid, cardiac function classification and the CGA score are the risk factors of the mortality rate of inpatients with decompensated CHF.
